Abstract: A power tong having a self-contained hydraulic power system within its rotating body converts mechanical energy from at least one mechanical link to hydraulic energy within the self-contained hydraulic power system. Energy applied from the non-rotating portion of the power tong is transferred to the mechanical link that links the fixed portion with the rotating portion of the power tong thus removing the need for rotary seals. The mechanical energy transferred to the self-contained hydraulic power system within the rotating body is used to extend and retract one or more grippers in contact with, for example, a tubular of well equipment drill strings.

Abstract: A pipe handling apparatus for handling pipe stands and stands of collars. The pipe handling apparatus improves the safety and efficiency of a rotary drilling operation. The pipe handling apparatus is integrated with a derrick monkey board, away from the heavy machinery within the derrick. The pipe handling apparatus is used for handling, storing and replacing pipe stands during the tripping out and tripping in processes.
